`pkg-config'
command (see http://pkgconfig.freedesktop.org/), whereas the second one uses `airtsp-config'
script. These methods are shortly described below.`stdair.m4'
), from the configuration script (generated thanks to `configure.ac'
).
AirTSP Dependencies
`pkg-config'
is a helper tool used when compiling applications and libraries. It helps you insert the correct compiler and linker options. The syntax of the `pkg-config'
is as follows:
pkg-config <options> <library_name>
For instance, assuming that you need to compile an AirTSP based program `my_prog.cpp'
, you should use the following command:
g++ `pkg-config --cflags airtsp` -o my_prog my_prog.cpp `pkg-config --libs airtsp`
For more information see the `pkg-config'
man pages.
`airtsp-config`
, which is installed by default in `$prefix/bin'
(`/usr/local/bin'
) directory. It can be used to simplify compilation and linking of AirTSP based programs. The usage of this script is quite similar to the usage of the `pkg-config'
command.
Assuming that you need to compile the program `my_prog
.cpp' you can now do that with the following command:
g++ `airtsp-config --cflags` -o my_prog_opt my_prog.cpp `airtsp-config --libs`
A list of `airtsp-config'
options can be obtained by typing:
airtsp-config --help
If the `airtsp-config'
command is not found by your shell, you should add its location `$prefix/bin'
to the PATH
environment variable, e.g.:
export PATH=/usr/local/bin:$PATH
`AM_PATH_AirTSP'
macro (specified in the M4 macro file), the following Makefile variables are then defined:`AirTSP_VERSION'
(e.g., defined to 0.23.0)`AirTSP_CFLAGS'
(e.g., defined to `-I${prefix}/include'
)`AirTSP_LIBS'
(e.g., defined to `-L${prefix}/lib -lairtsp'
)`LD_LIBRARY_PATH'
environment variable might be used to inform the linker of the dynamic library location, e.g.: export LD_LIBRARY_PATH=<AirTSP installation prefix>/lib:$LD_LIBRARY_PATH
